This is the best adress in Silom,
I come to bangkok around 3 times a year and I always book Ed's apartment.
The staff at the frontdesk is very friendly and can always help you if you need something, the district is quite convenient because you have two seven eleven at less than 200m from the condo and the skytrain is just in the corner of the street! If you want me to talk about equipment and cleanliness, there's nothing to say except everything was perfectly done everytime I come.
I like this district because it is quite convenient to stay there when you're on a business trip like me sometimes, or for holidays because you can go to many restaurants, mall and the nightlife is nice with nightclubs, bars and patpong night market.
I recommend and I'll come back again soon!
